Reissued Sept. 22, 1931 UNITED STATES PA ENT OFFICE CHARLES A. MESSMER, JR., ST. LOUIS, MISSOURI, ASSIGNOR TO BENJAMIN W. FREEMAN, OF CINCINNATI, OHIO SHOE ORNAMENT ING MACHINE Original No. 1,696,442, dated December 25, 1928, Serial No. 102,444, filed April 16, 11926. Application for reissue filed February 17,

This invention relates generally to shoe ornamenting machines, and has more particular reference to a die that is especially useful when employed in a clicking press to i; cut out blanks for the various parts of the uppers of boots and shoes and the like.

Such presses are customarily provided with anvils presenting a Wooden surface for engagement with the cutting edges of the die, in order to provide a surface which is softer than the cutting edges so as not to nick or'dull the latter, and which permits the die to sink deeply enough thereinto to v insure positive slitting of the material by the is cutting edges. After each operation the die is shifted to a different position on the wooden surface so that the latter presents a fresh surface to the cutting edges during the succeeding operation; The prevailing practice heretofore has beento place theleather or other stock material in a different position on the wooden surface for each operation, and then'to set the die in'an appropriate position thereon, after which the actuation of the press is initiated and its head brought down upon the die, forcing the latter through the material. The proper placing of the die with relation to the stock'prior to each operation is, however, attended with difficulties, since there is no means provided to determine the exact location of the die relatively to the stock, and the proper positioning of the die and the output of the press therefore depends largely upon the skill of the operator.

Accordingly, theprimary purpose of this invention is to provide means wherebythe die may be readily shifted after each operation to a new position over the wooden surface, and whereby the proper and expeditious placing ofthe stock with relation to the die will be facilitated. Other objects and advantages will appear in the course of the following description of a preferred embodiment of this invention. l

and associated parts comprising this invention;

Figure 2 is a fragmentary plan view of the plate for determining the location of the stock with reference tothe cutting edges of the die, showing the manner of placing the stock thereon prior to the cutting operation;

Figure 3 is a longitudinal vertical central sectional View through the device as it appears in the press during the cutting operation; and

Figure 4 is a view similar to'that of Figure 2, but showing the stock as it appears after having been blanked out by the die.

The device comprises a pair of plates 1 and 2, preferably formed of sheetsteel and pivoted together at their rear edges 3 and 4, respectively, by means of suitable hinges 5. The plate 1 is placed upon the wooden block or anvil 6 ofthe press and constitutes a. means or a member for holding the blank or stock of material in a definite position with relation to the cutting edges of the die during the cutting operation. The plate 1 is provided with an opening 7 therethrough whose edges 8 conform to the outline 9 of-the blank or sheet of leather 10 to be placed therein, as-shown in Figure 2. Gauge pins 11 are aflixed to the plate 1 and project from the upper side thereof along the edges 8. The said pins llassist the edges 8 in locating the blank 10. The plate 2 constitutes a member ormeans for holding a die 12,7secured thereto by'means of screws 13, thus forming a mounting for the die. The plate'2 preferably has an opening 14 therethrough which registers with the opening 15 extending through the die 12 and defined by the cutting edges 16 thereof. When plate 2 is swung inwardly or closed upon plate 1, the cutting edges 16 of die 12 are brought against the blank 10 and in proper relation to the outline of the blank, as determined by the locating edges 8 and pins 11 of the 'plate' l. That portion of plate 2 to which the "di'e'is secured is preferably arranged'paralleland in proper spaced relation to the plate 1 by'reason of the offset bends 17 and 18 in the plate 2; The intermediate portion of therear end of plate 2 is preferably :struck out'or separated from the outer .6' to limit the outward swing'of the plate'or die-holding member. 2, preferably to a. position slightly beyond the vertical,.as shownin Figure The manner of using the device' will be readily comprehended. The device-is placed on the wooden block or anvil 6 on the lower or stationary jaw of'the clickin press, with the plate 1 resting thereon ant the plate'2 swung "open slightly beyond. its vertical position, as shown in Figure I. i The blank 10 is placed in the opening 7 with its edges?) abutting against the edges 80f the opening. The plate E is then swung. inwardly, bringing the cutting edges 16 of thefdie against the blank 10. The press is then started, causing the head 21 on the upper jaw of thepress to de scend on the plate 2, thereby sinking the cutting edges. Ifithrough the blank 10 and into the block 6. After-the ascension ofhead 21,

the devicefis opened andthe-died-out blank 10, shown in Figure 4, is removed. The device is nowshifted to adiflerent position on the Wooden block and the foregoing" operation may berepeaxted. It will be observed thatthe die does notobscnre the blank as it isbeing placed in position on theblock 6., and the die. will always be locatedin proper relation totheblank at the time of cutting the i i On accountoi the. bend I8 whichmay be made either high. or low, the entire fitted-upper ofia shoe may be laid between the: plates landfls I Having, thus fully described this invention, I. hereby reserve the benefit ofa-ll changes in form, arrangement, order, or use of parts, as it is evident that many minor changes ma be made th'erein without departing from the lowing claims.
